Members of The North American Sundial Society and Analemma Society will be participating in the 3rd USA Science & Engineering Festival. Mark your calendars for Saturday and Sunday April 26 and 27th at the Walter E. Washington Convention Center in Washington DC. This is a Science, Technology, Engineering and Mathematics (STEM) exposition. In recognition of the Festival’s role in making STEM a national priority, Congress recently designated the last week in April as National Science Week.

NASS and the Analemma Society along with other expo presenters have more than 3,000 hands-on activities. NASS and the Analemma Society will introduce students and families to a variety of sundials and offering hands-on activities to cut them out and test them using a solar heliograph. It's all free. Come and learn about Sundials – The World’s Oldest Clocks.

The Science & Engineering Festival will also have a book fair—complete with signings by well-known science authors. Bill Nye the science guy will be there as well as Mike Rowe (Dirty Jobs on Discover Channel), Nate Bell (Design Squad on PBS) and the cast and crew from TV shows like Big. Bang Theory, as part of over 100 live stage performances.
